The men's Patagonia Piton Hybrid Vest takes the edge off of cold conditions. The construction relies on durable Polartec® Wind Pro® Hardface® fabric on the front, wrapping over the shoulders and down to mid-back, to shed snow and fend off wind. On the sides and back, the vest utilizes super breathable, stretchy and wicking Polartec Power Dry® fabric, creating a body-mapped design for use as a moderate-conditions outer layer until it’s time to don a full-on shell. The single zippered chest pocket and two zippered handwarmers are pack- and harness-compatible, while an absence of shoulder seams allows pack-wearing comfort. Polartec Hardface Technology enhances the Deluge® DWR (durable water repellent) finish for increased water repellency and abrasion-resistance.
